On the Geo Performance LifeTime plugin we've used a bootstrap action to import the center coordinates for each country. Using the jVectorMap we've added those points as markers to show the Application performance for each country. Something like this:

It is open source, take a look! You also have Maps for the US, Europe, etc.
Check the jVector Map official site for more details and feel free to add more maps to the jVectorMap component! :)
